For example, the front cover 402 a can beused as an input device that is equipped with a touch screen functionwhile serving as an output device that outputs a screen. The rear cover402 b is mounted to face a direction opposite to the front cover 402 a,and can be made of a material that is capable of transmitting a wirelesselectromagnetic wave or a magnetic field (e.g., a tempered glass or asynthetic resin). The plates (e.g., the front cover 402 a and the rearcover 402 b) are mounted on the housing 401 to form the exterior of theelectronic device 400 together with the housing 401.

According to various embodiments, the conductive pattern unit 405 can bemounted on a surface of the housing 401 that is opposite to the circuitboard 441.

The connection piece 555 can provide a means forconnecting the conductive patterns 553 a, 553 b, and 553 c to thecontrol circuit, the communication module, or the like of the electronicdevice (e.g., the electronic device 101, 201, or 400 of FIG. 1, 2, 4A,or the like). For example, one end of each of the conductive patterns553 a, 553 b, and 553 c can be positioned on the connection piece 155,and can be connected to the control circuit or the communication modulethrough a connection member, such as a connector, a pogo pin, or aC-clip.

When the conductive pattern unit 505 is viewed from the upper side(e.g., when the conductive pattern unit 505 disposed in the housing 501is viewed from the rear side of the electronic device 100), theconductive patterns 553 a, 553 b, and 553 c can be arranged such thatthe conductive patterns are adjacent to each other, such that theconductive patterns partially overlap with each other, and/or such thatone conductive pattern encloses another conductive pattern. A specificembodiment of the present disclosure discloses an example in which eachof the first, second, and third conductive pattern 553 a, 553 b, and 553c is formed on the base member 551, and the first conductive pattern 553a is arranged to be enclosed by the second conductive pattern 553 band/or the third conductive pattern 553 c.

According to various embodiments, the first conductive pattern 553 a caninclude a plurality of turns of a conductive line wound in a circularshape or a polygonal shape, and when the base member 551 is mounted inthe housing 501, the first conductive pattern 553 a can be arrangedsubstantially parallel to the housing 501 or the plate (e.g., the rearcover 402 b). The first conductive pattern 553 a can be connected to thecontrol circuit (e.g., the control circuit 857 of FIG. 8) so as totransmit/receive a wireless electromagnetic wave or power, or togenerate a magnetic field.

According to various embodiments, each of the second conductive pattern553 b and the third conductive pattern 553 c can include a plurality ofturns of a conductive line wound to form a circular shape, a polygonalshape, or a closed loop shape formed by a combination of a curve lineand a straight line. The second conductive pattern 553 b and/or thirdconductive pattern 553 c can be arranged to be substantially parallel tothe housing 501 or the rear cover 402 b. Each of the second conductivepattern 553 b and the third conductive pattern 553 c can be connected tothe control circuit so as to transmit/receive a wireless electromagneticwave or power, or to generate a magnetic field.

According to various embodiments, the second conductive pattern 553 band/or the third conductive pattern 553 c can be arranged in thesubstantially same plane as the first conductive pattern 553 a. In oneembodiment, when the base member 551 is in the form of a multi-layercircuit board, the first conductive pattern 553 a, the second conductivepattern 553 b, and/or the third conductive pattern 553 c can be formedin different layers, respectively. Even if the first conductive pattern553 a, the second conductive pattern 553 b, and/or the third conductivepattern 553 c are formed in the different layers of the multi-layercircuit board, respectively, the first conductive pattern 553 a, thesecond conductive pattern 553 b, and/or the third conductive pattern 553c can be arranged in the substantially same plane when the base member551 is in the form of a film. In arranging the first conductive pattern553 a, the second conductive pattern 553 b, and/or the third conductivepattern 553 c, each of the conductive patterns can be in the form of aclosed loop shape, and can be arranged such that the conductive patternsare adjacent to each other, such that one conductive pattern enclosesone or two other conductive patterns, and/or such that the conductivepatterns do not at least partially overlap with each other.

According to various embodiments, each of the first to third conductivepatterns 553 a, 553 b, and 553 c can transmit/receive a wirelesselectromagnetic wave, can transmit/receive wireless power, or cangenerate a magnetic field. According to various embodiments, accordingto the control of the control circuit, a wireless electromagnetic wavecan be transmitted/received, wireless power can be transmitted/received,or a magnetic field can be generated, through one conductive pattern orthrough a combination of two or more conductive patterns.

According to various embodiments, on a line that connects the controlcircuit to each of the first to third conductive patterns 553 a, 553 b,and 553 c, for example, a matching circuit, a lumped element, and/or aswitch element can be arranged so as to adjust, for example, a resonancefrequency of each of the conductive patterns or a magnetic fluxdistribution. For example, when the control circuit includes a wirelesscharge module and an NFC module, it is possible to cause the firstconductive pattern 553 a to perform one of the wireless charge functionand a near field communication function by connecting the firstconductive pattern 553 a to one of the wireless charge module and theNFC module using the switch element. On each line that connects thefirst conductive pattern 553 a to one of the wireless charge module andthe NFC module, for example, a matching circuit can be arranged toadjust the operation characteristic of the first conductive pattern 553a to be suitable for each of the functions.

According to various embodiments, the control circuit can furtherinclude a magnetic secure transfer (MST) module. Each of the first tothird conductive patterns 553 a, 553 b, and 553 c can be connected atleast one of the wireless charge module, an NFC module, and an MSTmodule so as to conduct at least one of the wireless charge function,the NFC function, and the MST function under the control of the controlcircuit. A conductive pattern connected to the MST module can generate amagnetic field under the control of the control circuit.

According to one embodiment, unlike those illustrated in FIGS. 5A and5B, the NFC transaction coil (the first conductive pattern 553 a), theMST transaction coil (the second conductive pattern 553 b), and thewireless charge coil (the third conductive pattern 553 c) within theelectronic device can be configured in the form of a circle, and all thecenters of the circles of respective coils coincide with each other.According to one embodiment, among the plurality of coils, the NFCtransaction coil is subjected to modulation in a frequency band (e.g.,15 MHz) that is higher than those of two remaining coils, and is thecoil that gets the most interference from a peripheral coil antenna.Thus, the NFC transaction coil can be mounted in the outermost areaamong the plurality of coils. According to one embodiment, the MSTtransaction coil can have a size that coincides with the operating rangeof the corresponding coil. Accordingly, the MST transaction coil can bemounted in the middle area of the plurality of coils. A shunt capacitoror a serial inductor can reduce the resonance frequency of the coil to alow frequency, which can consequently result in an effect of causing theresonance frequency to be spaced away from the resonance frequency ofthe NFC transaction coil. Among the plurality of coils, the MSTtransaction coil and the wireless charge coil conduct communication at alower frequency and transmit a higher power compared to the NFCtransaction coil, and thus can be less affected by a peripheral coilthan the other coils. According to one embodiment, a coupling preventioncircuit of the transaction coil can be mounted at the output end of theMST transaction coil. In such a case, the resonance frequency of the MSTcoil can be operated due to the parasite of the inductor of NFCtransaction coil.

FIG. 6 is a plan view illustrating a flat coil 653 according to variousembodiments of the present disclosure.

Referring to FIG. 6, the flat coil 653, which transmits/receives awireless electromagnetic wave or generates a magnetic field, can takevarious shapes, but can take a circular shape or a polygonal shape whichis substantially vertically and horizontally symmetric. For example, theflat coil 653 can be formed of a plurality of turns of a conductive linewound on a base member in a circular or polygonal shape.

FIG. 7 shows graphs representing exemplary measurement values that wereobtained by measuring magnetic fluxes generated by each conductivepattern of the electronic device 400 (e.g., the electronic device 101)according to various embodiments of the present disclosure.

In FIG. 7, the graph indicated by “f1” represents a distribution ofmagnetic fields (e.g., magnetic fluxes, or magnetic flux density, B)when a current was applied to the flat coil which is vertically andhorizontally symmetric. Magnetic fluxes generated by a symmetric flatcoil (e.g., the flat coil 653 of FIG. 6) can be symmetric with referenceto a predetermined point (e.g., a central point). As described above, byusing the magnetic fluxes generated by the symmetric flat coil, variousinformation items (e.g., transaction information) can be transmittedto/received from an external device (e.g., a POS terminal).

According to various embodiments, a reader header of a magnetic readingtype POS terminal can receive transaction information or the like when amagnetic recording medium, such as a magnetic stripe, comes in contacttherewith or when magnetic fluxes are generated within a recognitiondistance range of the reader header. In the magnetic reading type POSterminal, a magnetic recording medium, such as a magnetic stripe, (or amagnetic flux generating medium, such as a coil) should come in directcontact with the reader header or should be positioned within therecognition distance range of the reader header. The user can use such amagnetic recording medium (or the magnetic flux generating medium, suchas a coil) while carrying it. For example, when magnetic fluxes of alevel to be recognizable by the reader header are generated by the flatcoil in a wide range to be recognizable by the reader header, the readerheader can recognize and receive the information (e.g., transactioninformation) that is transmitted through the magnetic fluxes generatedby the flat coil.

According to various embodiments, while the flat coil can be easilymounted in an electronic device that is carried by the user, themagnetic flux-generated area or the intensity of the generated magneticfluxes can be restricted. For example, while the flat coil mounted inthe electronic device can generate the magnetic fluxes in an area thatis proportional to the size of the electronic device, the intensity ofthe magnetic fluxes can be restricted in consideration of powerconsumption, interference with an external transceiver (e.g., anantenna) or the like. In addition, in a vertically and horizontallysymmetric coil, a null point or section (indicated by “NULL” in FIG. 7)is formed in the central area so that the transaction information or thelike may not be smoothly transmitted. The “null section” can refer to apoint, an area, and/or a section in which the fluxes generated accordingto a current flow of a flat coil are offset with each other so that theintensity of the magnetic fluxes (or the overall magnetic flux density,B) is relatively weaker than other areas.

According to various embodiments, the electronic device 400 (e.g., theelectronic device 101) can shift or suppress the null section NULL orcan generate stronger magnetic fluxes (higher magnetic flux densities)by variously designing, in forming the conductive patterns 553 a, 553 b,and 553 c on a flat coil, for example, conductive pattern unit 505 ofFIG. 5B, a partial thickness (or width) of the conductive lines thatform the conductive patterns 553 a, 553 b, and 553 c, arrangement areasof the conductive lines, the number of conductive lines, or the like.For example, referring to the graph indicated by “f2” in FIG. 7, thenull section NULL can be shifted leftward from the central portion onthe base member 751 (e.g., the base member 551 of FIG. 5A), and strongerfluxes (higher flux densities) can be generated between the null sectionNULL and the right end of the base member 751. Various embodimentsrelated to the structure of the conductive patterns will be described inmore detail with reference to FIG. 12.

FIGS. 8 and 9 are views illustrating application forms of a conductivepattern unit of an electronic device 400 according to one of variousembodiments of the present disclosure (e.g., the electronic device 101illustrated in FIG. 1).

Referring to FIG. 8, conductive materials arranged on a housing 801 ofthe electronic device (e.g., the housing 501 of FIG. 5A) can beconnected to a conductive pattern (e.g., the above-mentioned thirdconductive pattern 553 c of FIG. 5A) to form a current flow CF path.

According to various embodiments, at least a part of the housing 801(hereinafter, referred to as a “conductive member 919”) of theelectronic device can be formed of a conductive material, and one pointof the conductive member 919 can be connected to the control circuit 857and another point can be connected to one of the conductive patterns(e.g., the third conductive pattern 853 c). The control circuit 857 canapply a signal current to the third conductive pattern 853 c, and by thesignal current applied to the third conductive pattern 853 c, a currentflow CF path can be formed along the third conductive pattern 853 c anda part of the conductive member 819. For example, the third conductivepattern 853 c and a part of the conductive member 819 can be formed by aflat coil. According to various embodiment, the conductive member 819can include a slit (not illustrated) that is formed across a part of theconductive member 819 so that the conductive member 819 can have anelectric characteristic, such as an electric length (e.g., an electriclength corresponding to a resonance frequency) or an inductance.

According to another embodiment, the loop antenna (coil antenna) cantake a form that interconnects a pattern implemented on an FPCB and amechanical element of the electronic device (terminal). At least a partof the exterior of the electronic device (terminal) can include aconductive material (e.g., a metal) that allows a current to flow therethrough. In addition, when at least some portions of the exterior of theelectronic device (terminal) are separated (is not electricallyconnected), the portions can be electrically interconnected through aconnection element. The connection element can be a passive element,such as an inductor or a capacitor, or a structure that contains aconductive material.

Referring to FIG. 9, in housing 901 of the electronic device (e.g., theelectronic device 400 illustrated in FIG. 4A), a conductive pattern(e.g., a flat coil) can be formed only by a part of the conductivemember 819. For example, the conductive member 819 can be formed alongat least a part of the circumference of an opening O formed on thehousing 901, and as the control circuit 957 applies a signal current tothe conductive member 919, a current flow CF path can be formed alongthe circumference of the opening O. For example, apart from theabove-described conductive pattern unit (e.g., the conductive patternunit 505), a flat coil can be formed using the conductive member 919that forms a part of the housing 901. According to various embodiments,since the conductive member 919 includes a slit (not illustrated) thatis formed across the conductive member 919, the conductive member 919can have an electric character, such as an electric length (e.g., anelectric length corresponding to a resonance frequency) or aninductance.

Although not illustrated in the drawings, the loop antenna can beconnected to a component including a coil (or an inductor) within theelectronic device. For example, a coil (or an inductance) that is formedwithin a component of the electronic device, such a speaker, a motor, ora pen can be electrically connected to the loop antenna so as to be usedas a loop antenna.

According to still another embodiment, the loop antenna can be formed ona display panel unit. The loop antenna can be implemented in the lowerend of the cover glass using a transparent electrode.

While FIGS. 8 and 9 illustrate the current flow path CF in one direction(e.g., the counterclockwise direction), the current flow path can beformed to be different from the direction illustrated in FIGS. 8 and 9according to a signal current applied by the control circuit 857 or 957.In addition, the current flow path and the direction thereof can be morevariously changed in consideration of, for example, the position wherethe conductive material is disposed on the housing 801 or 901.

FIG. 10 is a block diagram for describing configurations of a conductivepattern unit 1005 and a control circuit 1057 in an electronic device 400(e.g., the electronic device of FIG. 1) according to one of variousembodiments of the present disclosure.

Referring to FIG. 10, the control circuit 1057 can include at least oneof a wireless charge module 1057 a, an NFC module 1057 b, and an MSTmodule 1057 c. The control circuit of FIG. 10 can be the control circuit857 of FIG. 8. Each of the wireless charge module 1057 a, the NFC module1057 b, and the MST module 1057 c can take an independent IC chip form,and two or three modules can be integrated and formed in an IC chip. Forexample, in a specific embodiment of the present disclosure, the controlcircuit 1057 is described with reference to an example in which thewireless charge module 1057 a, the NFC module 1057 b, and/or the MSTmodule 1057 c are integrated. However, it shall be noted that it doesnot mean that the control circuit 1057 is an IC chip in which thewireless charge module 1057 a, the NFC module 1057 b, and/or the MSTmodule 1057 c are integrated. The conductive pattern unit 1005 caninclude at least one of the first to third conductive patterns 1053 a,1053 b, and 1053 c.

According to various embodiments, the wireless charge module 1057 a canwirelessly receive power through the conductive pattern unit 1005 andcan charge a battery (e.g., the battery 443 of FIG. 4A). The wirelesscharge module 1057 a can be individually or selectively connected toeach of the first to third conductive patterns 1053 a, 1053 b, and 1053c through a switch member (not illustrated). For example, between thewireless charge module 1057 a and at least one of the first to thirdconductive patterns 1053 a, 1053 b, and 1053 c, the switch member isdisposed so as to connect at least one of the first to third conductivepatterns 1053 a, 1053 b, and 1053 c to the wireless charge module 1057a. On a line that interconnects the switch member and each of the firstto third conductive patterns 1053 a, 1053 b, and 1053 c, a matchingcircuit or the like can be disposed to make each of the first to thirdconductive patterns 1053 a, 1053 b, and 1053 c suitable for wirelesspower transmission/reception.

According to various embodiments, the NFC module 1057 b can conduct nearfield communication through the conductive pattern unit 1005. The NFCmodule 1057 b can be connected to each of the first to third conductivepatterns 1053 a, 1053 b, and 1053 c through a switch member (notillustrated). On a line that interconnects the switch member and each ofthe first to third conductive patterns 1053 a, 1053 b, and 1053 c, amatching circuit or the like can be disposed to make each of the firstto third conductive patterns 1053 a, 1053 b, and 1053 c suitable fornear field communication.

According to various embodiments, the MST module 1057 c can generatemagnetic fluxes through the conductive pattern unit 1005. For example,the MST module 1057 c can generate magnetic fluxes through at least oneof the first to third conductive patterns 1053 a, 1053 b, and 1053 c soas to transmit information (e.g., transaction information) to anexternal device (e.g., a magnetic recording type POS terminal). Forexample, the electronic device (e.g., the electronic device 101 ofFIG. 1) can periodically transmit an MTS signal, in which transactioninformation is included, several times through the MST module. Forexample, the MST signal can include transaction information that isincluded in at least a part of a credit card.

According to various embodiments, the MST module 1057 c can be connectedto each of the first to third conductive patterns 1053 a, 1053 b, and1053 c through a switch member (not illustrated). On a line thatinterconnects the switch member and each of the first to thirdconductive patterns 1053 a, 1053 b, and 1053 c, a matching circuit orthe like can be disposed to allow magnetic fluxes to be generated usingthe first to third conductive patterns 1053 a, 1053 b, and 1053 c.

According to various embodiments, when the MST module 1057 c is in thestate of being connected to the third conductive pattern 1053 c throughthe switch member, the wireless charge module 1057 a or the NFC module1057 b can be controlled not to be connected to the third conductivepattern 1053 c. When the third conductive pattern 1053 c is in the stateof being connected to the NFC module 1057 b through the switch member,the MST module 1057 c can be controlled to be connected to the firstconductive pattern 1053 a and/or the second conductive pattern 1053 bwhen a condition at which magnetic fluxes should be generated occurs. Inthis way, the control circuit 1057 can select and operate a suitable oneamong the first to third conductive patterns 1053 a, 1053 b, and 1053 caccording to an operation condition or a command that occurs in theelectronic device.

FIG. 11 is a block diagram for describing a configuration fortransmitting transaction information from an electronic device 400according to one of various embodiments of the present disclosure (e.g.,the electronic device 101 of FIG. 1).

In various embodiments of the present disclosure, a configuration forgenerating magnetic fluxes using the above-mentioned conductive pattern1153 c (e.g., the third conductive pattern 553 c illustrated in FIG. 5cor the like) will be described. However, the description will not limitthe present disclosure, and the configuration, the operation, or thelike of the third conductive pattern disclosed in various embodiments tobe described later can be implemented through the first conductivepattern 553 a and/or the second conductive pattern 553 b illustrated inFIG. 5A or the like.

Referring to FIG. 11, a conductive pattern 1153 c according to variousembodiments (e.g., the third conductive pattern 553 c illustrated inFIG. 5A or the like) can be formed by a plurality of turns of a singleconductive line that is wound in a polygonal shape or extends, and caninclude first and second sections 1153 d and 1153 e that includeconductive lines having different specifications, respectively.

FIG. 12 is a plan view illustrating an exemplary conductive pattern 1253c for transmitting transaction information in an electronic deviceaccording to various embodiments of the present disclosure (e.g., theelectronic device 101 of FIG. 1).

Referring to FIG. 12, the conductive coil portions disposed in the firstsection 1253 d in the area where the conductive line forming theconductive pattern 1253 c (e.g., the third conductive pattern 553 cillustrated in FIG. 5A) is arranged can have a width wider than that ofthe conductive line portions arranged in the second section 1253 e. Forexample, in FIG. 12, the third conductive pattern 1253 c (e.g., thethird conductive pattern 553 c illustrated in FIG. 5A or the like) canbe formed by a flat coil having a vertically asymmetric shape.

According to one embodiment, the conductive pattern 1253 c can be a loopantenna. The conductive pattern 1253 c can be designed to have differentintensities of magnetic fields from area to area. A shadow area of theconductive pattern (e.g., the above-mentioned null section NULL), whichoccurs within the electronic device (terminal), can be shifted. Forexample, the width of the antenna pattern (e.g., the conductive line) ofthe first section 1253 d can be implemented to be wider than the antennapattern arranged in the second section 1253 e. As a result, when acurrent flows, the resistance of the area of the first section 1253 dbecomes lower than that of the second section 1253 e, and thus, theintensity of the magnetic field generated in the first section 1253 dcan be stronger than the intensity of the magnetic field generated inthe second section 1253 e. In the case where the intensity of themagnetic field generated in the first section 1253 d is stronger thanthe intensity of the magnetic field generated in the second section 1253e, the shadow area of the loop antenna can be formed in the lower endportion of the electronic device (terminal) rather than in the centralportion of the electronic device (terminal). For example, as in FIGS. 28to 31, while the transaction is being performed, the electronic device(e.g., the electronic device 101 of FIG. 1) can indicate an MSTrecognition range (e.g., the “area between the center to the upper endof the electronic device (terminal)”) so as to cause the user to bringthe MST recognition range close to a reader so that the recognition rateof the MST can be improved. According to one embodiment, even if thethickness of the pattern in the first section 1253 d area is the same,separate conductive patterns can be formed in the lower end of the firstsection 1253 d area, and thus, the intensity of the generated magneticfluxes can be implemented more strongly.

FIG. 13 is a graph representing exemplary measurement values obtained bymeasuring magnetic fluxes generated by the conductive patternillustrated in FIG. 12.

Referring to FIG. 13, the magnetic fluxes generated by the conductivepattern 1353 c (e.g., the third conductive pattern 553 c illustrated inFIG. 5A or the like) can have an asymmetric shape. For example, themagnetic fluxes generated in the first section 1353 d can be larger thanthe magnetic fluxes generated in the second section 1353 e. In addition,as the magnetic fluxes radiated from the first section 1353 d on theconductive pattern 1353 c (e.g., the third conductive pattern 553 cillustrated in FIG. 5A or the like) increases more and more, the nullsection NULL can be shifted to be offset to the direction where thesecond section 1353 e is positioned from the central portion of theconductive pattern 1353 c (e.g., the third conductive pattern 553 cillustrated in FIG. 5A or the like).

According to various embodiments, as described above, in a verticallyand horizontally symmetric flat coil, a null section occurs in thecentral portion, and symmetric magnetic fluxes are generated. When theflat coil illustrated in FIG. 12 is manufactured to be the same as thesymmetric flat coil in terms of an arrangement area and the number ofturns of the conductive line and the same signal current is appliedthereto, the flat coil illustrated in FIG. 12 (e.g., the thirdconductive pattern 553 c illustrated in FIG. 5A or the like) cangenerate magnetic fluxes of which the null section is shifted from thecentral portion to one side edge. Alternatively, it will be understoodthat the flat coil illustrated in FIG. 12 radiates magnetic fluxes fromthe first section to a wider area than the symmetric flat coil.Accordingly, compared to the symmetric flat coil, information (e.g.,transaction information) can be easily transmitted to an external device(e.g., a magnetic reading type POS terminal) through the magnetic fluxesgenerated by the conductive pattern 1353 c (e.g., the third conductivepattern 553 c illustrated in FIG. 5A or the like).

FIGS. 14 to 18 are plan views illustrating various exemplary conductivepatterns for transaction information transmission in the electronicdevice (e.g., the electronic device 101 of FIG. 1) according to one ofvarious embodiments of the present disclosure, respectively.

Referring to FIG. 14, in arranging one conductive coil that forms theconductive pattern 1453 c (e.g., the third conductive pattern 553 cillustrated in FIG. 5A or the like), even if the conductive coilportions of the same number of turns are arranged in each of the firstand second sections 1453 d and 1453 e, the conductive coil portionsarranged in the first section 1453 d can be arranged to be distributedin a wider area. For example, by forming the first section 1453 d in anwider area than the second section 1453 e, the null section NULL can beshifted from the central portion of the conductive pattern 1453 c (e.g.,the third conductive pattern 553 c illustrated in FIG. 5A or the like)to one side (e.g., the lower side in FIG. 14), and more magnetic fluxescan be radiated from the first section 1453 d.

Referring to FIG. 15, in arranging one conductive line that forms theconductive pattern 1553 c (e.g., the third pattern 553 c illustrated inFIG. 5A or the like), a plurality of turns wound in the form of a coilcan be arranged in each of the first and second sections 1553 d and 1553e. The plurality of turns wound in the form of a coil in each of thefirst and second sections 1553 d and 1553 e can generate a current flowin the same direction (e.g., counterclockwise). According to a signalcurrent applied to the conductive line that forms the third conductivepattern 1553 c, the current generated in the first and second sections1553 d and 1553 e can flow clockwise.

According to various embodiments, the coil arranged in the first section1553 d can be arranged to occupy a wider area and more turns compared tothe coil arranged in the second section 1553 e. For example, in thefirst section 1553 d, the conductive line can be arranged to be woundfive times, and in the second section 1553 e, the conductive coil can bearranged to be wound three times. By setting the number of turns of thecoil and the area in which the coil is arranged to be different fromsection to section, the null section NULL can be shifted from thecentral portion of the third conductive pattern 1553 c (e.g., the thirdconductive pattern 553 c illustrated in FIG. 5A or the like) to one side(e.g., upward in FIG. 15), and more magnetic fluxes can be radiated fromthe first section 1553 d. In addition, according to one embodiment, evenif the number of turns arranged in the first section 1553 d and thenumber of turns arranged in the second section 1553 e are the same, thenull section can be formed on one side (e.g., the area between the nullsection and the third conductive pattern in FIG. 12) from the centralportion of the third conductive pattern 1553 c (e.g., the thirdconductive pattern 553 c illustrated in FIG. 5A or the like). Accordingto one embodiment, the null section formed according to the shape ofFIG. 15 can be more widely distributed compared to the case where theareas occupied by respective sections are the same. That is, asdescribed above, the position where the null section is formed and thearea of the section where the magnetic fluxes are radiated can varydepending on the arrangement of the conductive pattern.

Referring to FIG. 16, in arranging one conductive line that forms thethird conductive pattern 1653 c (e.g., the third conductive pattern 553c illustrated in FIG. 5A or the like), a plurality of turns wound in theform of a coil can be arranged in each of the first and second sections1653 d and 1653 e. The plurality of turns, which are wound in the formof a coil in each of the first and second sections 1653 d and 1653 e,can generate current flows in the opposite directions (e.g., clockwiseand counterclockwise directions) in relation to each other,respectively. For example, when the current flow generated in the firstsection 1653 d is formed in the counterclockwise direction, the currentflow generated in the second section 1653 e can be formed in theclockwise direction.

The coils, which are formed in the first and second sections 1653 d and1653 e by the conductive line, respectively, can be formed in the samearea while being different from each other in the number of wound times(e.g., the number of turns). For example, the coil arranged in the firstsection 1653 d can have more turns, and the magnetic fluxes radiatedfrom the first section 1653 d can be more than the magnetic fluxesradiated from the second section 1653 e. Accordingly, the null sectionNULL of the magnetic fluxes radiated by the conductive pattern 1653 c(e.g., the third conductive pattern 553 c illustrated in FIG. 5A or thelike) can be shifted from the central portion of the conductive pattern1653 c (e.g., the third conductive pattern 553 c illustrated or thelike) to one side (e.g., the upper side in FIG. 16), and more magneticfluxes can be radiated from the first section 1653 d. In addition,according to one embodiment, when the number of turns of the coilarranged in the first section 1653 d is the same as the number of turnsarranged in the second section 1653 e, the magnetic fluxes generated bythe coils arranged in the plurality of sections can be furtherconcentrated to the central portion C of the conductive pattern 1653 c(e.g., the third conductive pattern 553 c illustrated in FIG. 5A or thelike) so that the recognition rate of the MST module can be enhanced.That is, as described above, depending on the arrangement of theconductive patterns, the null section forming position and the area ofthe magnetic flux radiation section can be differently formed.

Referring to FIGS. 17 and 18, the conductive pattern 1753 c or 1853 c(e.g., the third conductive pattern illustrated in FIG. 5A or the like)can be formed in the form of a coil. For example, the first section 1753d or 1853 d is arranged in the central portion and the second section1753 e or 1853 e can be arranged to enclose the periphery of the firstsection 1753 d or 1853 d. The first section 1753 d or 1853 d is formedto occupy a smaller area than the second section 1753 e or 1853 e, butcan include more conductive line portions than the second section 1753 eor 1853 e. For example, the first section 1753 d or 1853 d can includemore conductive line portions in a narrow area or space, like a solenoidcoil, so that the first section 1753 d or 1853 d can radiate moremagnetic fluxes than a flat coil (e.g., a coil formed by conductivelines in the second section). For example, the magnetic fluxes radiatedby the second section 1753 e or 1853 e can be horizontally symmetricwith reference to the central portion, and the null section can beformed in the central portion. The first section 1753 d or 1853 d can bearranged in the central portion of the second section 1753 e or 1853 eand can radiate strong magnetic fluxes to compensate the null section ofthe magnetic fluxes formed by the second section 1753 e or 1853 e. Forexample, each of the third conductive patterns 1753 c or 1853 cillustrated in FIGS. 17 and 18 can generate magnetic fluxes of which theintensity increases from the peripheral edge toward the central portion.

The shapes of the conductive patterns described in the above-describedvarious embodiments can be used for forming the first conductive pattern553 a and/or the second conductive pattern 553 b illustrated in FIG. 5Aor the like. According to another embodiment, the present disclosure isnot necessarily limited to the conductive patterns of theabove-described various embodiments (e.g., the third conductive pattern553 c illustrated in FIG. 5A or the like), and the conductive patternscan be variously formed according to a direction, to which it is desiredto shift the null section and/or an area in which it is desired to forma stronger magnetic field and/or magnetic fluxes by shifting the nullsection.

As described above, according to various embodiments of the presentdisclosure, the conductive patterns (e.g., the above-mentioned thirdconductive pattern 153 c) can provide a plurality of current flow paths.For example, first and second current flow paths can be provided and itis possible to design such that the directions of the currents flowingin the first and second paths are the same. According to variousembodiments of the disclosure, the conductive patterns can furtherprovide a third current flow path, and according to the direction andintensity of the current flowing in each of the first to third paths,and the arrangement of the conductive lines, each of which forms one ofthe path, the null section can be shifted to be close to one side of theconductive patterns (e.g., to the lower side of the conductive patterns)and a stronger magnetic field and/or magnetic fluxes can be generated inthe other side (e.g., in the upper portion and/or central portion of theconductive patterns).

FIG. 19 illustrates a block diagram for describing another exemplaryconfiguration for transaction information transmission of an electronicdevice 400 according to one of various embodiments of the presentdisclosure (e.g., the electronic device 101 of FIG. 1).

Referring to FIG. 19, according to various embodiments, a conductivepattern 1953 c (e.g., the third conductive pattern 553 c illustrated inFIG. 5A or the like) can include a plurality of coils 1953 f and 1953 g,the same signal can be applied to each of the coils from a controlcircuit (e.g., the MST module 1957 c). For example, the third conductivepattern 1953 c can include first and second coils 1953 f and 1953 g thatare arranged to be independent from each other, the same signals can besimultaneously applied to the first and second coils 1953 f and 1953 gfrom the MST module 1957 c. The first and second coils 1953 f and 1953 gcan be arranged to be adjacent to each other.

According to various embodiments, when the conductive pattern 1953 c(e.g., the third conductive pattern 553 c illustrated in FIG. 5A or thelike) is formed in a multi-layer circuit board, (e.g., a flexibleprinted circuit board, the first and second coils 1953 f and 1953 g canbe formed in the same layer or different layers (or surfaces) of theflexible printed circuit board. According to various embodiments, whenthe first and second coils 1953 f and 1953 g are formed in differentlayers of the flexible printed circuit board, the first and second coils1953 f and 1953 g can be arranged to be adjacent to each other or topartially overlap with each other when viewed from the upper side of theflexible printed circuit board.

FIGS. 20 to 23 are plan views illustrating various exemplary conductivepatterns for transaction information transmission in an electronicdevice 400 according to one of various embodiments of the presentdisclosure (e.g., the electronic device 101), respectively.

Referring to FIG. 20, the first and second coils 2053 f and 2053 g, towhich the same signals are simultaneously applied from the MST module(e.g., the MST module 1957 c of FIG. 19) can be arranged to have thesame specifications (e.g., such that the conductive lines have the samenumber of turns and occupy the same area while being wound in the samedirection). When the same signals are simultaneously applied to thefirst and second coils 2053 f and 2053 g, the first and second coils2053 f and 2053 g generate current flows in the same direction (e.g., inthe clockwise direction). The conductive pattern 2053 c (e.g., the thirdconductive pattern 553 c illustrated in 5A or the like), which is formedof the first and second coils 2053 f and 2053 g, can generate magneticfluxes of which the null section is positioned to be offset to one sideor the other side depending on the magnetic fluxes generated by each ofthe first and second coils 2053 f and 2053 g.

Referring to FIG. 21, the first and second coils 2153 f and 2153 g,which receive the same signals simultaneously applied from the MSTmodule (e.g., the MST module 1957 c of FIG. 19), can be formed such thatthe conductive lines are wound in the opposite directions while beingarranged to have the same number of turns and to occupy the same area.When the same signals are simultaneously applied to the first and secondcoils 2153 f and 2153 g, the first and second coils 2153 f and 2153 gcan generate current flows in the opposite directions in relation toeach other. For example, when the first coil 2153 f generates a currentflow in the clockwise direction, the second coil 2153 g can generate acurrent flow in the counterclockwise direction. The conductive pattern2153 c (e.g., the third conductive pattern 553 c illustrated in FIG. 5Aor the like) formed of the first and second coils 2153 f and 2153 g cangenerate magnetic fluxes of which the null section is positioned to beoffset to one side or the other side according to the magnetic fluxesgenerated by each of the first and second coils 2153 f and 2153 g.

Referring to FIG. 22, the first and second coils 2253 f and 2253 g,which receive the same signals simultaneously applied from the MSTmodule (e.g., the MST module 1957 c of FIG. 19), can be arranged to havedifferent numbers of turns and to occupy different areas. When the samesignals are simultaneously applied to the first and second coils 2253 fand 2253 g, the second coil 2253 g, which is formed to occupy a largerarea while having more turns, can radiate more magnetic fluxes than thefirst coil 2253 f. For example, when the same signals are applied to thefirst and second coils 2253 f and 2253 g arranged as illustrated in FIG.22, respectively, the null section generated by the conductive pattern2253 c (e.g., the third conductive pattern 553 c illustrated in FIG. 5Aor the like) formed of the first and second coils 2253 f and 2253 g canbe formed to be offset to the left side from the central portion.

According to various embodiments, the first and second coils forming theconductive pattern (e.g., the third conductive pattern 553 c illustratedin FIG. 5A or the like) can take the form of a flat coil arranged in thesame plane, but can take the form of a solenoid coil. For example,referring to FIG. 23, the conductive lines forming the first coil 2353 fcan take a form in which they are wound on the outer peripheral surfaceof the housing 2301 of the electronic device 2300 while being arrangedto extend in the longitudinal direction of the electronic device 2300,while the conductive lines forming the second coil 2353 g can take aform in which they are wound on the outer peripheral surface of thehousing 2301 of the electronic device 2300 while being arranged toextend in the width direction of the electronic device 2300.

According to various embodiments of the present disclosure, when theconductive pattern (e.g., the third conductive pattern 553 c illustratedin FIG. 5A or the like) takes the form of a flat coil, the magneticfluxes generated by the conductive pattern (e.g., the third conductivepattern 553 c illustrated in FIG. 5A or the like) can be radiated towardone surface (e.g., the rear surface) of the electronic device 101 or theother surface (e.g., the front surface) of the electronic device 101.Alternatively, according to various embodiments of the presentdisclosure, when the third conductive pattern takes the form of asolenoid coil as illustrated in FIG. 23, the magnetic fluxes can beradiated in more directions (e.g., in the directions toward the upperend, lower end and/or side) compared to the case where the thirdconductive pattern takes the form of a flat coil. When the first andsecond coils are formed as flat coils, any one of the conductivepatterns (e.g., the third conductive pattern 553 c illustrated in FIG.5A or the like) illustrated in FIGS. 12 to 18 can be included.

While FIG. 23 illustrates the first and second coils 2353 f and 2353 gby dotted lines for the convenience of illustration and description, theconductive lines that form the first and second coils 2353 f and 2353 gcan be formed of a transparent material (e.g., an indium-tin oxide). Forexample, even if the first and coils 2353 f and 2353 g are arranged onthe display device 2302 a, it is possible to prevent image quality frombeing deteriorated

FIGS. 24A to 24F are views for another exemplary configuration fortransaction information transmission in an electronic device accordingto one of various embodiments of the present disclosure (e.g., theelectronic device illustrated in FIG. 1).

Referring to FIG. 24A(a), according to various embodiments, theconductive pattern 2453 c (e.g., the third conductive pattern 553 cillustrated in FIG. 5A or the like) can include a plurality of coils2453 f and 2453 g, and a signal can be independently applied to each ofthe coils 2453 f and 2453 g from a control circuit (e.g., the MST module2457 c). For example, the conductive pattern 2453 c can include firstand second coils 2453 f and 2453 g which are independently arranged inrelation to each other, and the same signals or different signals can besimultaneously applied to the first and second coils 2453 f and 2453 gfrom the MST module 2457 c. The first and second coils 2453 f and 2453 gcan be arranged to be adjacent to each other. The conductive pattern2453 c (e.g., the third conductive pattern 553 c illustrated in FIG. 5Aor the like) can generate magnetic fluxes in variously differentdistributions according to a time point when a signal is applied to eachof the first and second coils 2453 f and 2453 g, a time interval forwhich a signal application state is maintained, or the direction of asignal current.

According to various embodiments of the present disclosure, theelectronic device can sense an alignment state with an external deviceand can differently set the time point when a signal is applied to eachof the first and second coils 2453 f and 2453 g, a time interval forwhich a signal application state is maintained, or the direction of asignal current. For example, according to the repetition of an actionthat brings the electronic device 2400 (illustrated in FIG. 24D) to theexternal device or the moving direction of the electronic device 2400,according to an alignment angle and distance between the electronicdevice 2400 and the external device, or according the location where theelectronic device 2400 is gripped by the user, the rotation of theelectronic device 2400, or the inclined angle of the electronic device2400, a signal can be applied to each of the first and second coils 2453f and 2453 g such that magnetic fluxes, which are easily transmitted tothe external device, can be generated.

For example, first and second signals, which are different from eachother, can be applied to the first and second coils 2453 f and 2453 g,respectively. In consideration of the relative positions or the likebetween the electronic device 2400 and the external device, the firstand second signals can be applied, simultaneously, sequentially,alternately, and/or partially overlapping in time, to the first andsecond coils 2453 f and 2453 g, respectively. The first and secondsignals can be equal to each other.

According to various embodiments, the first and second signals can causethe first and second coils 2453 f and 2453 g to generate current flowsin the same direction or in different directions. For example, when thefirst signal is applied to the first coil 2453 f for a predeterminedlength of time to generate a current flow in a first direction, thesecond signal may not be applied to the second coil 2453 g. In anothertime interval, when the second signal is applied to the second coil 2453g to generate a current flow in a second direction, the first signal maynot be applied to the first coil 2453 f. The first and second directionsof the current flows, which are generated by the first and second coils2453 f and 2453 g, respectively, can be equal to each other or differentfrom each other.

According to various embodiments, the control circuit (e.g., the controlcircuit 857 of FIG. 8) can variously control the time points when thefirst and second signals as described above are applied, an applicationpattern, a time interval for which the application state is maintained,the direction of the signal current, etc. according to the alignmentstate between the electronic device 100 and the external device and/orwhether the information transmission is successful.

According to various embodiments, the conductive pattern 2453 c (e.g.,the third conductive pattern 553 c illustrated in FIG. 5A or the like)includes a plurality of coils, and the shapes and arrangements of thecoils forming the conductive pattern 2453 c (e.g., the third conductivepattern 553 c illustrated in FIG. 5A or the like) in the structure wherethe signal is independently applied to each of the coils can be similarto those of the embodiments described above with reference to FIGS. 19to 23. Accordingly, detailed descriptions for the shapes or arrangementsof the coils forming the conductive patterns 2453 c (e.g., the thirdconductive pattern 2453 c illustrated in FIG. 5A or the like) accordingto the present embodiments will be omitted. According to variousembodiments, each of the above-described first and second coils 2453 fand 2453 g can be formed of a part or the entirety of any one of theconductive patterns of the embodiments described above with reference toFIGS. 5B to 18. According to various embodiments, each of theabove-described first and second coils 2453 f and 2453 g can be formedof any one of the conductive patterns of the embodiments described abovewith reference to FIGS. 5B to 18 or a combination of two or more of theconductive patterns.

Referring to FIG. 24A(b), the plurality of coils can include a firstcoil (e.g., the first coil 2453 f of FIG. 24A(a)) and a second coil(e.g., the second coil 2453 g of FIG. 24A(a)), and the first coil or thesecond coil can be electrically connected to the MST module 2457 c orthe wireless charge module 2457 a.

For example, according to one embodiment, the MST module 2457 c canapply the same signals or different signals through a plurality of coilswithin the MST module 2457 c. According to one embodiment, the samesignals or different signals can be simultaneously applied to the firstand second coils, respectively, from the MST module 2457 c or thewireless charge module 2457 a. For example, according to the time pointswhen the signals are applied to the first and second coils,respectively, the time intervals for which signal application states aremaintained, or the directions of the signal currents, the conductivepattern (e.g., the conductive pattern 2453 c of FIG. 24A(a)) cangenerate magnetic fluxes in variously different distributions.

For example, the MST module 2457 c can transmit transaction informationthrough one or more of the first coil and the second coil. For example,the MST module 2457 c can select one or more of the first coil and thesecond coil according to a pre-set selection condition, and can transmitthe transaction information through the selected coil(s). The pre-setselection condition can include a case in which the selection is madebased on the distance between the external device to receive thetransaction information and the electronic device. For example, the MSTmodule 2457 c can transmit the transaction information through theselected one of the first coil and the second coil, and can transmit thetransaction information again through the other non-selected one of thefirst and second coils based on whether a response to the transactioninformation is received or based on the response contents. For example,the MST module 2457 c can be set to transmit the transaction informationthrough the selected one of the first coil and the second coil, and inresponse to the response indicating that the transaction information hasbeen received, to refrain from a connection between the selected coiland the external device.

For example, the wireless charge module 2457 a can acquire power fromone or more of the first coil and the second coil or can transmit power.

FIG. 24B is a view illustrating a plurality of coils according tovarious embodiments of the present disclosure.

Although not illustrated, the NFC can operate in a polling mode duringthe transmission of an MST signal. The electronic device 2400 (e.g., theelectronic device 101 of FIG. 1) can transmit a signal to a POS terminalat least once through one or more coils (e.g., the first coil 2453 f andthe second coil 2453 g), and the signal can include pulses indicatingthe entire transaction information (the entirety of first transactiondata and/or second transaction data). Among signals transmitted for onesec, one or more pulses can include different data. As another example,one or more pulses can be transmitted through different MST modules(coil antennas), respectively. Although not illustrated, during thetransmission of the MST signal, the NFC can operate in a polling mode.

Referring to FIG. 24B(a), among a plurality of coils, when a current inthe counterclockwise direction flows in the first coil 2453 f and nocurrent flows in the second coil 2453 g, a null can be formed in thecentral portion of the first coil 2453 f among the plurality of coilsand no null can be formed in a portion corresponding to the second coil2453 g.

Referring to FIG. 24B(b), when a current in the counterclockwisedirection flows in the second coil 2453 g and no current flows in thefirst coil 2453 f among the plurality of coils, a null can be formed inthe central portion of the second coil 2453 g among the plurality ofcoils and no null can be formed in a portion corresponding to the firstcoil 2453 f.

In the case where only one coil is selected among the first coil 2453 fand the second coil 2453 g as in FIGS. 24B(a) and 24B(b), a current iscaused to alternately flow in the selected coil, and transactioninformation is transmitted to an external POS terminal only through theone selected coil in which the current alternately flows, a null can bealternately formed only in the central portion of the one coil among thefirst coil 2453 f and the second coil 2453 g. Thus, even if a reader ofthe POS terminal is provided in the central portion of each coil, thetransaction information can be transmitted to the POS terminalregardless of whether the null is formed.

As illustrated in FIG. 24B(c), the null sections, which are generated bythe first coil 2453 f and the second coil 2453 g, respectively, may notoverlap with each other. According to various embodiments, an electronicdevice 2400 (e.g., the electronic device 101 of FIG. 1) can transmit asignal to the POS terminal through a plurality of coils at least once,and can generate a sequence of a plurality of signals using firsttransaction information and/or second transaction information. Forexample, the electronic device 101 can transmit a transaction signalthrough the first coil 2453 f in a first MST signal section, and cantransmit the transaction signal through the second coil 2453 g in thesecond MST signal section. As a result, while the transaction progresses(e.g., while the MST signal is transmitted 16 times), the electronicdevice 101 can give an effect as if the null section of a magnetic fieldinput to the reader of an external device (a POS terminal) moves. Whenthe reader of the external device (the POS terminal) is positioned in afirst null section, the electronic device 101 can complete thetransaction by receiving an input of transaction information of a secondsection that is transmitted through the second coil 2453 g, or cancomplete the transaction by receiving an input of transactioninformation of the MST signal section. As another example, an electronicdevice 2400 (e.g., the electronic device 101) can transmit a signal tothe POS terminal at least once through one or more coils, and cangenerate a sequence of a plurality of signals using first transactioninformation and/or second transaction information. The electronic devicecan store instructions that cause the sequence of the plurality ofsignals to be magnetically transmitted to the outside through aconductive pattern (e.g., the third conductive pattern 2453 c of FIG.24A). One or more signals among the sequence of the plurality of signalscan include pulses indicating the entirety of first transactioninformation and/or second transaction information (the entirety of thefirst transaction data and/or the second transaction data).

As illustrated in FIG. 24B(d), the first coil 2453 f and the second coil2453 g can be, but not exclusively, arranged in an upper/lower structurein relation to each other within an electronic device 2400 (e.g., theelectronic device 101 of FIG. 1).

FIG. 24C illustrates a plurality of coils according to variousembodiments of the present disclosure.

Referring to FIG. 24C(a), according to various embodiments, when acurrent in a first direction (e.g., a counterclockwise direction) flowsin the first coil 2453 f and a current in a second direction (e.g., aclockwise direction) flows through the second coil 2453 g, the magneticfluxes generated by the first coil 2453 f and the magnetic fluxesgenerated by the second coil 2453 g can transmit transaction informationto an external device while forming nulls in the central portion of thefirst coil 2453 f and the central portion of the second coil 2453 g,respectively.

Referring to FIG. 24C(b), according to various embodiments, when acurrent in a first direction (e.g., a clockwise direction) flows in thefirst coil 2453 f and the second coil 2453 g, the magnetic fluxesgenerated by the first coil 2453 f and the magnetic fluxes generated bythe second coil 2453 g can transmit transaction information to anexternal device while forming a null in a central portion between thefirst coil 2453 f and the second coil 2453 g.

When currents in the same direction and currents in opposite directionsare caused to flow in the first coil 2453 f and the second coil 2453 galternately with a specific time interval as in FIGS. 24C(a) and 24C(b),transaction information can be more easily transmitted to a POS terminalregardless whether a null is formed even if the reader of the POSterminal is provided in the central portion of each coil or in thecentral portion between two coils.

The methods described above with reference to FIGS. 24B and 24C can beused in a mixed manner.

FIG. 24D is a view illustrating one method of transmitting transactioninformation according to various embodiments of the present disclosure.

Referring to FIG. 24D(a), according to various embodiments, when a card(e.g., a magnetic card) 2411 comes in contact with a POS terminal (e.g.,a POS reader) 2413 and is swiped, the POS terminal 2413 can receivetransaction information called “A” from the card 2411.

According to various embodiments, an electronic device 2400 (e.g., theelectronic device 101 of FIG. 1) can receive transaction information(e.g., Track 1, Track 2, Track 3, or token information) included in atleast a part of a magnetic stripe of the card 2411 from a card companyserver or a bank server through a communication module, and can storethe transaction information in a processor (e.g., the processor of FIG.2) or a separate embedded security module in a necessary form.

According to various embodiments, the magnetic card (e.g., the card 2411of FIG. 24D(a)) can store data for each of Track 1, Track 2, and Track3. The card reader (e.g., the POS terminal 2413 of FIG. 24D(a)) can beprovided with a header and a coil to read the data recorded in thetracks (magnetic stripe tracks) of the magnetic card. When a track ofthe magnetic card (e.g., a magnetized black line) is swiped at theposition of the header in the rail portion of the card reader, magneticforce lines, which pass through the coil connected to the header, can bechanged. A current corresponding to the change of the magnetic forcelines is generated in the carder reader, and the card reader can readand process the data recorded in the track from the current. In otherwords, the static magnetic field associated with the magnetic stripe,when the card is swiped through the reader, results in a time-varyingmagnetic flux linking the pick-up coil arrangement, and that changingmagnetic flux causes a corresponding voltage to be induced.

According to various embodiments, the electronic device (e.g., theelectronic device 2400 of FIG. 24D(b)) can store the data recorded inthe tracks of the magnetic card, and can be provided with a module formagnetic field communication (e.g., an MST module). The MST module canput the data, which are recorded in the tracks, in the magnetic fieldsignal to transmit the data to the card reader through an antenna (e.g.,the first coil 2453 f and the second coil 2453 g of FIG. 24D(b)). Then,a current, which is the same as the current generated when the magneticcard is swiped at the position of the header of the card reader, can begenerated in the card reader. That is, the user can pay costs or thelike by bringing the electronic device to be close to the card reader orto come in contact with the carder.

According to various embodiments, the data put in an MST signal andtransmitted by the MST module can be transmitted in the form of token.In a transaction method using the token, not Tracks 1, 2, and 3 but atleast a part of data of Tracks 1, 2, and 3 can be substituted with atoken or a cryptogram. For example, in Track 1, 2, and 3, PAN can besubstituted with a token. Additional data and discretionary data inTracks 1 and 2, and use and security data and additional data in Track 3can be substituted with a cryptogram. Substituted values can beconverted into bits and the bits can be put in the MST signal to betransmitted to the card reader. For example, when the track data formatis used, the token information can be sent to the card company withoutseparately making a change in the card reader. Here, the token caninclude an ID for identifying the card. In addition, the token caninclude information for identifying the card company. Transaction datacan include the expiration date of the card, a merchant ID, etc. and canbe made by combining some pieces of information related to atransaction.

According to various embodiments, the electronic device 2400 cangenerate a magnetic field signal. For example, the magnetic field signalgenerated in the electronic device 2400 can be a signal similar to amagnetic field signal that is generated as the card 2411 is swiped inthe card reader of a card reading device (or a POS terminal) 2413. Forexample, a user can pay purchase costs or the like by bringing aportable electronic device (e.g., the electronic device 2400), which hasgenerated a magnetic field signal, to be close to or to come in contactwith the card reading device (e.g., a POS terminal 2413) without using aseparate magnetic card (e.g., the card 2411).

According to one embodiment, the transaction information transmitted byat least one coil (e.g., the coil 2453 f or 2453 g of FIG. 24D) caninclude data in a token form including information for the transactioncard. For example, the data in the token form can include tokeninformation and cryptogram information, the token information caninclude card identification (ID) information received from a cardcompany, and the cryptogram information can include transaction datawhich can include at least one of expiration date information of thecard used at the time of transaction and card member storeidentification (ID) information received from the POS terminal.

According to one embodiment, at least one coil (e.g., the coil 2453 f or2453 g of FIG. 24d ) can transmit the first track data, the second trackdata, and the third track data to the POS terminal in a form in whichone or more track data are substituted with token information andcryptogram information by the control circuit. For example, among thetrack data, AD (Additional Data) and DD (Discretionary Data) can besubstituted with the cryptogram information, and PAN information can besubstituted with token information. In this case, there is an advantagein that because data of track units, which have been used when using theexisting card, can be used in transmitting the transaction information,the transaction can be performed only with the token information withoutchanging separate data on the POS terminal.

According to one embodiment, among the one or more coils, the first coil2453 f can transmit the data of the first track to the POS terminal, andthe second coil 2453 g can transmit the data of the second track to thePOS terminal.

According to various embodiments, even in the case where the electronicdevice is provided with a plurality of coils rather than a single coil,each of the plurality of coils can have the shapes that have describedabove with reference to FIGS. 11 to 18. Referring to FIG. 24D(b),according to various embodiments, one coil selected among a first coil2453 f and a second coil 2453 g that are provided in the electronicdevice 2400, for example, the first coil 2453 f can transmit transactioninformation including at least a part of transaction information “A”,which is transmitted by a card 2411 to a POS terminal 2413, to the POSterminal 2413 in the form of magnetic fluxes (or, in other words, in theform of a magnetic signal). In addition, the second coil 2453 g, whichis alternately selected with the first coil 2453 f, can transmittransaction information including at least a part of the transactioninformation “A” to the POS terminal 2413 in the form of magnetic fluxes.

Even in the case where a signal including transaction information istransmitted to an external device (e.g., a POS terminal) using a singlecoil rather than a plurality of coils as described above with referenceto FIGS. 24D(a) and 24D(b), the above-described method is alsoapplicable. For example, one first coil (e.g., the coil 2453 f) cantransmit transaction information including at least a part of thetransaction information “A” to the POS terminal 2413 in the form ofmagnetic fluxes.

FIG. 24E is a view illustrating another method of transmittingtransaction information according to various embodiments of the presentdisclosure.

Referring to FIG. 24E(a), according to various embodiments, when a card2411 is swiped through a POS terminal 2413 in a first direction (e.g.,from top to bottom), the POS terminal 2413 can receive first transactioninformation called “A” from the card 2411. Referring to FIG. 24E(b),when the card 2411 is swiped through the POS terminal 2413 in a seconddirection (e.g., from bottom to top), the POS terminal 2413 can receivesecond transaction information called “B” from the card 2411.

Referring to FIG. 24E(c), according to various embodiments, in order tocause the electronic device 2400 to transmit the first transactioninformation “A” and the second transaction information “B”, the firstcoil 2453 f and the second coil 2453 g of the electronic device 2400 canbe alternately selected. Upon being selected, the first coil 2453 f cantransmit transaction information including at least a part of the firsttransaction information “A” to the POS terminal 2413, and the secondcoil 2453 g can transmit transaction information including at least apart of the second transaction information “B” to the POS terminal 2413.According to one embodiment, each of the alternately selected coils canselect transaction information of one or more of the first transactioninformation “A” and the second transaction information “B” according toa pre-set condition, and can transmit the transaction information to thePOS terminal.

FIG. 24F is a view illustrating still another method of transmittingtransaction information according to various embodiments of the presentdisclosure.

As illustrated in FIGS. 24F(a) and 24F(b), the electronic device 2400can select one of the first coil 2453 f and the second coil 2453 gaccording to a relative position or the distance between the electronicdevice 2400 and the POS terminal 2413, or according to a relativeposition or the distance between the first coil 2453 f or the secondcoil 2453 g and the POS terminal 2413. For example, as illustrated inFIG. 24F(a), when the distance between the first coil 2453 f and the POSterminal 2413 is shorter than the distance between the second coil 2453g and the POS terminal 2413, the electronic device 2400 can select thefirst coil 2453 f and can transmit transaction information to the POSterminal 2413 through the selected first coil 2453 f Unlike this, forexample, as illustrated in FIG. 24F(b), when the distance between thesecond coil 2453 g and the POS terminal 2413 is shorter than thedistance between the first coil 2453 f and the POS terminal 2413, theelectronic device 2400 can select the second coil 2453 g and cantransmit transaction information to the POS terminal 2413 through theselected second coil 2453 g. All the above-described transactioninformation transmission methods can be used by being variouslycombined.

FIG. 25 is a perspective view illustrating an electronic device 2500according to another embodiment among various embodiments of the presentdisclosure. The electronic device 2500 can be the electronic device 101of FIG. 1.

Referring to FIG. 25, the electronic device 2500 can include a main body2501 and wearing members 2502 a and 2502 b that extend from oppositesides of the main body 2501, respectively to be capable of being worn onthe user's body portion (e.g., a wrist). The electronic device 2500 caninclude conductive patterns 2553 c-1 and 2553 c-2 that radiate magneticfluxes. The conductive patterns 2553 c-1 and 2553 c-2 can be formed by apart or the entirety of one of the conductive patterns or coils of theabove-described embodiments, or can be formed of a combination of two ormore of the conductive patterns or coils of the above-describedembodiments. In the present embodiment, a plurality of conductivepatterns 2553 c-1 and 2553 c-2 can be arranged in the wearing members2502 a and 2502 b, respectively.

Among the conductive patterns, a first conductive pattern 2553 c-1 caninclude a flat coil 2553 f-1 and a solenoid coil 2553 g-1 that arearranged to be adjacent to each other (without overlapping with eachother). Among the conductive patterns, a second conductive pattern 2553c-2 can include a flat coil 2553 f-2 and a solenoid coil 2553 g-2 thatare arranged to partially overlap with each other. Each of theconductive patterns 2553 c-1 and 2553 c-2 can receive a signal currentapplied through a control circuit embedded in the main body 2501 toradiate magnetic fluxes, and can transmit information (e.g., transactioninformation) to an external device (e.g., a magnetic reading type POSterminal) through the radiated magnetic fluxes.

The NFC module 228 and the MST module canselectively send transaction information to an external device (e.g.,the POS terminal) according to a designated schedule or a signal period(e.g., 0.2 sec). The NFC module 228 and the MST module can selectivelyoperate in a designated time interval so as to reduce power consumptionaccording to the signal transmission, and to prevent duplicatetransactions. The user can conduct a transaction merely through anaction of bringing the electronic device 201 to come in contact with orto be close to a designated transaction reception device, even if theuser does not separately select a communication method.

According to one embodiment, the data reception module 3522 canrecognize a low/high state of the transferred pulse signal as data(e.g., 0 bit or 1 bit). Alternatively, the data reception module 3522can confirm the number of low-to-high transitions for a designatedlength of time, and can recognize the number as data. For example, whenthe number of low-to-high transitions for the designated length of timeis one, it can be recognized as 0 (zero) bit, and when the number istwo, it can be recognized as 1 (one) bit.

According to various embodiments, the output conversion module 3521 caninclude a circuit to convert the data recognized by the data receptionmodule 3522 into a form required for transfer to the MST module 3530.The circuit can include a first switch S1, a second switch S2, a thirdswitch S3, and a fourth switch S4.

According to thecontrol states of the switches, the directions of the voltages suppliedto the opposite ends of the coil antenna 3531 can be changed. At thistime, the voltage level supplied to the antenna can be zero bit or onebit. For example, in the case of zero bit, the first switch and thefourth switch can be turned ON and the second switch and the thirdswitch can be turned OFF, or vice versa. The output conversion module3521 can change the directions of the voltages (the direction of thecurrent) supplied to the opposite ends of the coil antenna L to besuitable for data recognized by the data reception module 3522, therebychanging the direction of the magnetic field transmitted to an externaldevice (e.g., the POS terminal) through the coil antenna L. This can besimilar to a magnetic field that is generated when a magnetic card isswiped through a POS card reader. Each of the switches S1, S2, S3, andS4 can include an N-type MOSFET, a P-type MOSFET, and a relay.

For example, the voltagesor currents transferred to the first MST module 4057 a and the secondMST module 4057 b can have different levels (magnitudes), respectively.For example, a first data reception module 4040 a and a second datareception module 4040 b within the MST control module 4030 can receiveone or more same signals from an MST data transmission unit 4010. Forexample, the first output conversion module 4041 a and the second outputconversion module 4041 b receive one or more same signals from the MSTdata transmission unit 4010 and transmits the received one or more samesignals from the MST data transmission unit 4010. For example, the MSTdata transmission unit 4010 can transmit MST signals (not illustrated)including the same transaction information to the first data receptionmodule 4040 a and the second data reception module 4040 b. In anotherexample, the MST data transmission unit 4010 can transmit a controlsignal (not illustrated) to activate the first MST module 4057 a and thesecond MST module 4057 b equally to the first data reception module 4040a and the second data reception module 4040 b. For example, in responseto the reception of the control signal, the MST control module 4030 cancontrol the first MST module 4057 a and the second MST module 4057 b tosend the MST signals to the outside.

According to one embodiment, when a plurality of MST output conversionmodules are provided as in FIG. 40B, the first data reception module4040 a and the second data reception module 4040 b within the MSTcontrol module 4030 can receive one or more same signals from the MSTdata transmission unit 4010.

The MST data transmission unit 4010 can transmitMST signals (not illustrated) including the same transaction informationto the first data reception module 4040 a and the second data receptionmodule 4040 b, and can transfer different control signals (notillustrated) to the first data reception module 4040 a and the seconddata reception module 4040 b, respectively, to independently control thefirst MST module 4057 a and the second MST module 4057 b, respectively.The first MST module 4057 a and the second MST module 4057 b can besequentially activated based on the control signals and can send a partof the MST signals, respectively. For example, the first MST module 4057a can be activated first to sequentially transmit a plurality ofsequences of signals. Then, the second MST module 4057 b can beactivated to sequentially transmit a plurality of sequences of signals.

According to one embodiment, the MST data transmission unit can transmitthe same pulse signals (including the same transaction information) tothe first data reception module and the second data reception module,and with respect to a control signal to activate each output conversionmodule, the MST data transmission unit can transfer different signals tothe first data reception module and the second data reception module sothat the first output conversion module and the second output conversionmodule can be independently controlled. For example, the first outputconversion module and the second output conversion module can besequentially activated based on the control signals. For example, thefirst output conversion module and the second output conversion modulecan be activated in an intersection manner to send signals to anexternal device (e.g., a POS terminal). For example, the first outputconversion module and the second output conversion module can besimultaneously activated. For example, the first output conversionmodule and the second output conversion module can be selectivelyactivated according to the state of the electronic device (terminal).For example, when NFC communication is activated in the electronicdevice (terminal) by using a loop antenna (or an antenna) adjacent tothe first output conversion module, the MST data transmission unit canactivate the second output conversion module to send the MST signals.For example, in the case where when a signal has been sent by activatingat least one of the first output conversion module and the second outputconversion module but the signal has not been recognized well, and thusthe user wishes to cause the signal to be recognized again by moving theelectronic device (terminal), the first output conversion module and thesecond output conversion module can be simultaneously activated. Forexample, when the electronic device (terminal) is vertically erected,the second output conversion module can be activated, and when theelectronic device (terminal) is horizontally laid, the first outputconversion module can be activated.

According to one embodiment, the MST data transmission unit can transmita control signal to activate the first output conversion module and thesecond output conversion module equally to the first data receptionmodule and the second data reception module, and can transmit differentpulse signals (including different transaction information) to the firstdata reception module and the second data reception module,respectively. For example, Track 1 information and Track 2 informationcan be transferred to the first data reception module and the seconddata reception module, respectively.

According to one embodiment, when a plurality of MST modules areprovided as in FIG. 40C, a first data reception module and a second datareception module within the MST control module can receive one or moresame signals from the MST data transmission unit 4010, and the firstoutput conversion module 4041 a and the second output conversion module4041 b receive one or more same signals from the MST data transmissionunit 4010 and transmits the received one or more same signals from theMST data transmission unit 4010.

According to one embodiment, the MST data transmission unit can transmitthe same pulse signals (including the same transaction information) tothe first data reception module and the second data reception module,respectively, and can transfer different control signals to the firstdata reception module and the second data reception module,respectively, to independently control the first MST module and thesecond MST module. For example, the first MST module and the second MSTmodule can also be sequentially activated based on the control signals.For example, the first MST module and the second MST module can activatein an intersection manner to send signals to an external device (e.g., aPOS terminal). For example, the first MST module and the second MSTmodule can be simultaneously activated. The first MST module and thesecond MST module can be selectively activated according to the state ofthe electronic device. For example, when short distance wirelesscommunication (e.g., NFC) is activated by using a coil antenna adjacentto the first MST module or when cellular network wireless communicationis activated by using an adjacent antenna, the MST data transmissionunit can activate the second MST module to send an MST signal. Forexample, when at least one of the first MST module and the second MSTmodule is activated to send a signal but the signal is not recognizedwell, and thus the user moves the electronic device to cause the signalto be recognized again, (i.e., when tagging occurs repeatedly), this canbe recognized by a sensor and the first MST module and the second MSTmodule can be simultaneously activated.

According to one embodiment, the MST data transmission unit can transmita control signal to activate the first MST module and the second MSTmodule equally to the first data reception module and the second datareception module, and can transmit different pulse signals (includingdifferent transaction information) to the first data reception moduleand the second data reception module, respectively. For example, Track 1information and Track 2 information can be transferred to the first datareception module and the second data reception module, respectively.
